"All documents in your or your agent's custody, control, or possession referring or relating to women alleging extramarital affairs with Donald Trump, payments by the President or anyone on his behalf to silence them, or any other potential campaign finance violation" would be subject to the the chairman's request, the letter states.

The Oversight committee has also requested an in-person interview with Falzone, who has said that she reached a settlement with Fox News that prevents her from speaking about the story.

Fox News did not immediately reply to a request for comment from The Hill.

The New Yorker reported that Falzone was told by her then-boss at Fox, Ken LaCorte, that the network's owner Rupert Murdoch wanted Trump to win the election, and therefore the story was killed.

“Good reporting, kiddo. But Rupert [Murdoch] wants Donald Trump to win. So just let it go," LaCorte reportedly said, according to The New Yorker.

Fox has denied that characterization, pointing to comments from a former executive who said last year that the network did not have enough factual evidence to report on Stormy Daniels's claims against the president.
